I’m tempted to call this a flying pig moment, but that would be culturally insensitive: A first for Saudis: Mozart performed publicly and women can attend.

RIYADH, Saudi Arabia - It’s probably as revolutionary and groundbreaking as Mozart gets these days. A German-based quartet staged Saudi Arabia’s first-ever performance of European classical music in a public venue before a mixed gender audience.

The concert, held at a government-run cultural centre, broke many taboos in a country where public music is banned and the sexes are segregated even in lines at fast food outlets.

The Friday night performance could be yet another indication that this strict Muslim kingdom is looking to open up to the rest of the world.

A few weeks ago, King Abdullah made an unprecedented call for interfaith dialogue with Christians and Jews: the first such proposal from a country that forbids non-Muslim religious services and symbols.

“The concert is a sign that things are changing rapidly here,” said German Ambassador Juergen Krieghoff, whose embassy sponsored the concert as part of the first-ever German Cultural Weeks in Saudi Arabia.

“Evidently the government has decided that a minimum of openness in our new world economy and in our information-based world is necessary for us and also for good understanding among cultures,” he added.

Public concerts are practically unheard of in the kingdom. Foreign embassies and consulates regularly bring musical groups, but they perform on embassy grounds or in expatriates’ residential compounds, and the shows are not open to the public.

In the past couple of months, however, there has been a quiet, yet marked increase in cultural activities in Saudi Arabia. Lectures and a couple of segregated folk music performances were held on the sidelines of Riyadh’s book fair. And Jiddah’s annual Economic Forum opened with a surprise this February: a performance of Arab and western music.

“For half an hour, we did not quite know whether we had stumbled into an unknown Jiddah nightclub or whether it was some amazing mistake that would suddenly stop,” wrote Michel Cousins in the English-language daily Arab News, describing the 30-minute show.
